GORE BIKE WEAR Visibility AS Vest. The name in windproof cycling gear is Gore Bike Wear, period. Gore's Visibility Active Shell Vest sports a half lock, underflap zipper that lets nothing through, and the legendary Windstopper layer which does just that. It's also highly breathable with excellent moisture transfer, so when things start to heat up you'll never be clammy. Elastic hems keep the vest in place no matter what your riding situation and a Napoleon pocket provides storage for slender essentials.
